Where is the exhaust leak , and what is a 'small' check?

Location of the leak is important. You could go to a parts store and get a patch kit for the exhaust depending on size and location of leak. Very inexpensive if you can go this route. http://www.autozone.com/autozone/accessories/Exhaust-Accessories/Exhaust-Repair/_/N-25hw?filterByKeyWord=exhaust+patch+&fromString=search They have different kits available.
